All questions are based on C++

1) In C++, arrays are passed by reference in functions.

A. true

B. false

2) In C++, two functions with the same function signature

but different return type can be overloaded.

A. true

B. false

3) In C++, class members are public by default.

A. true

B. false

4) In C++, all operators can be overloaded for user-defined

data types.

A. true

B. false

5) A friend function of a class can access the private

member variables of that class.

A. true

B. false

6) Protected members of a public base class become

public members of the derived class.

A. true

B. false

7) The base class constructor is called after the derived

class constructor.

A. true

B. false

8) A member function of a derived class may have the

same name as a member function of the base class.

A. true

B. false

9) C++ allows you to pass an object of a derived class as

an argument to a function where the parameter is of base

class type.

A. true

B. false

10) Any mathematical operation, including multiplication

and division, may be performed on a pointer.

A. true

B. false

11) In C++, array names are constant pointers.

A. true

B. false

12) In dynamic binding, the necessary code to call a

specific function is generated by the compiler during

compile-time.

A. true

B. false

13) Here is a function definition:

void func(int& i, int k)

{

i = 1;

k = 2;

}

Suppose that a main program has two integer variables x

and y and both are given the value 0. Then the main

program calls func(x,y); What are the values of x and y

after the function func finishes?

A. Both x and y still 0.

B. x is now 1, but y is still 0.

C. x is still 0, but y is now 2.

D. x is now 1, and y is now 2.

14) Here is a function prototype and some possible

function calls:

int sumOfThreeNumbers(int, int = 20, int = 30);

// Possible function calls:

cout << sumOfThreeNumbers ();

cout << sumOfThreeNumbers (23, 15);

cout << sumOfThreeNumbers (23, , -30);

cout << sumOfThreeNumbers (23, 15, -30);

How many of the above function calls are legal?
